报道了Ph_2PNEtC（O）NEtPPh_2和Ph_2PNMeC（S）NMePPh_2的合成。研究了Ph_2PNEtC（O）NEtPPh_2、Ph_2PNMeC（O）NMePPh_2和Ph_2PNMeC（S）NMePPh_2与Pt（II）、Pd（II）的配位化学。脲衍生物与MCl_2（cod）（M = Pd，Pt）反应生成简单的MCl_2L配合物。还制备了简单螯合物Mo（CO）_4L和Al_2ClAu-L-AuCl络合物的示范性实例。然而，使用Pd（OAc）2，形成含有水解配体（P-N键断裂）的双金属化合物[PdOPh 2 {N（Me）C（O）N（Me）PPh 2}]2。此外，硫脲化合物与PtCl 2（cod）反应得到[Pt{Ph 2 PN（Me）C（N（Me）HS）} Cl 2]，其为含有PtSCNP环的真正杂环。新化合物的光谱特征和六个配合物的X-射线结构的报告。
The preparation of Ph2PNEtC(O)NEtPPh2 and Ph2PNMeC(S)NMePPh2 is reported. The coordination chemistry of Ph2PNEtC(O)NEtPPh2, Ph2PNMeC(O)NMePPh2 and Ph2PNMeC(S)NMePPh2 with Pt(II) and Pd(II) has been studied. The urea derivatives react with MCl2(cod) (M = Pd, Pt) to give simple MCl2L complexes. Demonstrative examples of simple chelate Mo(CO)4L and bimetallic ClAu–L–AuCl complexes have also been prepared. However with Pd(OAc)2 bimetallic compounds [PdOPh2{N(Me)C(O)N(Me)PPh2}]2 containing hydrolysed ligands (P–N bond cleaved) are formed. Furthermore the thiourea compound reacts with PtCl2(cod) to give [Pt{Ph2PN(Me)C(N(Me)HS)}Cl2], a true heterocycle containing a PtSCNP ring. The new compounds have been characterised spectroscopically and the X-ray structures of six complexes are reported.
